“…Besides, the concept of chemistry is not only macroscopic (observable) but also microscopic (unobserved), symbolic images, such as symbols, formulas, reactions equations and graphics also require to have the ability think, not only understand but also analyze and have the skills to be able to solve problems with various solutions [2]. Seeing these problems, a teacher must make an effort to overcome the difficulties of students by providing treatment to instil valuable learning by construction knowledge of students so that they can develop skills in solving problems as well as being skilled and creative in an effort so that students can understand chemistry learning and have skills to improve learning performance in the chemistry learning [3,4,5,6,7,8].…”
